I don't see the equivalence. There's no My Nokia forum, social networking area, user profile section, or other (non-cracking) means whereby other My Nokia users could search for and learn your phone number. The only people who have access to your phone number as your My Nokia username are the same ones who have access to it anyway: the Nokia employees allowed to access the My Nokia database. I agree it's unpleasant that Nokia has forced the submission of that information with PR1.2, but I don't see how being able to log in using it on the My Nokia website makes the situation worse. The My Nokia login page is SSL encrypted, so your phone number in transit to My Nokia is as safe from Malory as your credit card number on its way to Amazon.
